Saddle embolus of abdominal aorta

This code describes an acute, life-threatening condition where a large blood clot (embolus) lodges at the bifurcation of the abdominal aorta, effectively blocking blood flow to both lower extremities and potentially the pelvic organs. This "saddle" configuration is critical due to its widespread ischemic impact.

Use this code for patients presenting with sudden onset of severe lower extremity pain, pallor, pulselessness, paresthesia, and paralysis (the "5 Ps") due to an embolus obstructing the aortic bifurcation. Documentation should clearly state "saddle embolus of abdominal aorta" or describe an embolus at the aortic bifurcation causing acute ischemia.

• Distinguish from other aortic emboli; this code specifically denotes the saddle configuration at the abdominal aorta's bifurcation.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, as it represents an acute, critical condition.
• Ensure documentation specifies "embolus" and not "thrombosis" as the etiology, as these have different code assignments.
